A paper hat is folded into the shape of a kite, as shown. A kite is shown. The left and right angles are right angles. The sides above the right angles are (3 x + 5) inches and (5 x + 1) inches. The sides below the right angle are (2 x + 1) inches and 5 inches.

What total length of ribbon is needed to line the two long sides of the hat?

10 in.
11 in.
20 in.
22 in.

do you have the measurements?

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
